FASTENING FOR BEDSTEADS.

SPECIFICATION forming part of Letters Patent No. 633,651, datedSeptember 26, 1899.

Application filed October 29, 1898. Serial No. 694,971. (No model.)

f0 (LIZ whom it may concern:

Be it known that I, KOBY KOHN, a citizen of the United States, residingat Lincoln, in the county of Lancaster and State of Nebraska, haveinvented certain new and useful Improvements in Fastenings forBedsteads, &c., of which the following is a specification.

My invention relates to fastenings for bedsteads, lounges, and otherlike articles, preferably of metals; and it consists of certain partsconstructed to engage, as fully set forth hereinafter and as illustratedin the accompanying drawings, in which- Figure l is a perspective viewof part of a bed-post and rail and connections,illustrating myimprovements, the rail in position prior to fastening. Fig. 2 is a planof Fig. 1, showing a modified form of rail-plate. Fig. 3 is a detailedsectional view; Fig. I, a part sectional view of the rail-plate. Fig. 5is a view of one of the rail-pins, and Fig. 6 is a modifieation.

The post A of the bedstead, couch, lounge, or other like article isgenerally provided at the point where the detachable rail is to beconnected with a boss or enlargement B, preferably cast upon the post,although any suitable means may be employed to support a flange a. Whenthe boss is of metal cast upon the post, the flange a is preferably madeby cutting it from sheet metal with one or more dovetailed or othersecuring projections b. As shown, there are two dovetailed projectionsb,and these are of such alength that their ends bear directly upon thepost A. This is important, as thereby the flange a is set with absolutecertainty in the proper vertical positionthatis,.in its proper positionrelative to the post. If there were no such bearing upon the post, theflange in casting or securing it in place might be tilted, and thiswould result in an insecure fastening of the rail or in preventing aproper adjustment of its parts. By making the boss of cast metal Isecure strength and rigidity and a means of securing the flange a, andby making the latter of wrought metal I am enabled to shape it withprecision and secure a toughness and elasticity which cast metal wouldnot afford.

The flange a is provided with one, two, or more slots 0, each enlargedat the upper end to receive the head 1 of a pin E, extending from theside of the rail 0, the stem 20f the pin being adapted to the narrowerpart of the slot, and the end of the pin is reduced to pass through ahole in the rail C and is longer than the thickness of the rail, so thatthe pin can be secured by spreading this end and forming a head 4,riveting it in place.

In securing the parts together the rail is brought to proper positionand the heads of the pins are passed through the enlarged ends of theslots 0, and by pressure on the rail the shanks 2 of the pins arecarried into the narrower parts of the slots, and the incli nation ofthe latter also carries the end of the rail toward the boss B until itis in close contact therewith, and the parts are thus firmly united.

Instead of having the pins E project directly from the rail itself Iprefer to provide a rail-plate F, which forms part of the rail itself oris, as shown, riveted to the side of the rail and bent outward at theend to form a flange e at an angle greater than a right angle to theface of the rail, so that its side face will bear on the boss only nearthe edge of the flange. This permits the edge of the flange e to take abearing against the face so at one side of the flange ft of the bossbefore the rail is fully down, and as the rail-plate F Will be formed ofsheet metal the flange e will spring out slightly, under the pressureexerted on it as the rail is forced fully downward, thus maintaining theparts under such tension as will effectively prevent them from beingloose and rattling. This result is further insured by providing thebearing-face 2B of the boss B with an outward incline 5 near the lowerend, Fig. 1, which forces outward the rail as it .takes its lowestposition.

The body of the plate F may be flat, as in Fig. 1 but preferably has anoffset 25, as shown in Fig. 2, carrying the rail C farther outward andgiving increased width for the bed. The projections b b may be of anynumber, size, and shape, preferably dovetailed, to prevent theflange-plate from being withdrawn from the boss. Instead of beingdovetailed they may be straight and perforated, as shown in Fig. 6. Theheads 1 of the pins E are preferably rounded at the inner edges, asshown, facilitating their introduction into the slots.

It will be seen that as above constructed ICO the rail can be applied toeither side of the bead equally well and that the parts are firml yunited without danger of becomingloose from jars or moving the bed, butthat they can be readily separated by a simple upward and lateralmovement of the rail.

I do not limit myself to the precise construction of the parts shown;but

I claim as my invention- 1. The combination of apost havinga flange aprojecting radially therefrom, and a side bearing-face 00, said flangehaving slots inclining downwardly and inwardly toward said bearing-face,and a rail provided with laterally-projecting pins E to engage in saidslots, and with a flange 6 extending laterally therefrom, at an obtuseangle to the face of the rail, to engage with its edge to bearing-facea: and yield under pressure to exert a spring effect between the parts,substantially as described.

2. The combination ofa post having a flange a projecting radiallytherefrom and a side bearing-face minclining outwardly at its lower end,said flange being provided with slots, and a rail provided withlaterally-projecting pins to engage in said slots, and with a flange eextending laterally therefrom, at an obtuse angle to the face of therail, to engage with its edge the bearing-face wand yield when forcedover the outwardly-inclined portion of the bearing-face, to exert aspring effect between.

the parts, substantially as described.

3. The combination of a post having a boss of cast metal, a flange awith dovetailed projections partly embedded in said boss with theiredges in direct contact with the post, and provided with inclined slots,substantially as set forth.

4. The combination of a post, boss 13 hav' ing a face x with an inclinedportion 8, a flange a, with inclined slots enlarged at the ends, and arail with pins E and a flange e, substantially as set forth.

5. The rail 0 provided with a plate F having a flange eand pins E and anoffset 2f, substantially in combination with the post and its bosshaving a face at and slotted flange a, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

KOBY KOHN.
